The reason for defragmenting a drive are virtual machines, of which I 
have quite a few. Since I am playing with thing like Oracle RAC, I 
frequently have to run 3 or 4 of them simultaneously. They perform 
visibly better if VMDK files are defragmented. The reason is simple to 
explain: a database full scan, which does a sequential scan on a virtual 
machine, will also do a sequential scan on the real drive if the 
underlying VMDK file is contiguous. If not, it will be translated into 
gazillion of small fragment scans, which can take time.
I don't really care about defragmenting /usr, /var or /opt. And with 3 or 
for VM's running, I don't have much memory for caching, even on my 16GB 
RAM desktop.
